Hi there Joe,
Thanks for reaching out! I can help you here…
Indeed the article describe how to do with WooCommerce tickets, but I see in your website, you are using RSVP tickets. For this type of tickets other template has to be modified, I’ll describe the steps to achieve this:
- Copy the template wp-content/plugins/event-tickets/src/views/tickets/rsvp.php
- Paste a copy of the file in wp-content/themes/your_active_theme/tribe-events/tickets/rsvp.php
- Edit the file in your theme and change in line 53 max="<?php echo esc_attr( $ticket->remaining() ); ?>" for max="1"
That should do the trick for you, please let me know if it works for you,
Have a great weekend,
Nico
